Patient Circuit Calibration
Before use on a patient, each patient circuit must be calibrated to the Model 3100B by following this
procedure:
CAUTION
1. Insert the stopper in the Patient Circuit “Y” and turn on the Bias Flow gas.
2. Set Max Pa Alarm to 59 cmH2O.
3. Rotate the Mean Pressure ADJUST control to “Max.”
4. Adjust the Bias Flow to 20 LPM.
5. Depress and hold RESET (Oscillator OFF).
6. Observe the Mean Pressure display and adjust the Patient Circuit Calibration screw for a
reading of 39–43 cmH2O.
Do not over adjust the Patient Circuit Calibration screw. Over adjustment may cause damage to the device. The
screw will reach a mechanical stop when it is at the adjustment limit. DO NOT FORCE THE SCREW PAST THIS
STOP!
Other Scheduled Periodic Calibration
There are two other functions within the Model 3100B HFOV which require periodic calibration
1. Control Package DC Power Supply.
2. Airway Pressure Monitor Transducer Calibration.
Maintenance of accurate calibration of these functions is extremely important to the proper function of
the Model 3100B HFOV. If at any time, a calibration discrepancy exists that cannot be solved by the
normal calibration procedures described below, do not attempt to treat a patient with the HFOV. Call
CareFusion immediately for assistance.
The calibration interval for these functions is tracked on the Elapsed Time Meter (24) on the Rear Panel
of the Control Package. A calibration must be performed at least every 2,000 hours or when a
discrepancy is noticed. A National Bureau of Standards traceable digital voltmeter and a National
Institute of Standards and Technology traceable pressure measurement transducer are required for
proper calibration of the Power Supply and the Airway Pressure Monitor.
To assure accurate setup, all periodic calibrations must be done with the Model 3100B HFOV at room
temperature and prior to extensive operation of the oscillator. If the oscillator is warm due to previous
operation, allow a non-operating cool-down interval of at least one hour before commencing calibration.
